' 'This invention relates toautomatic mechanism for themanufa ctureof-radio apparatus and particularly toatipping ofi -mechanism for useonan exhaust machine. In

machines of this character, it is customary to dispose the device tobe'exhausted, such as a vacuum tube with its tubulation, in aport onanintermittently moving turret. Upon movement of the turret, the-tube or{other article to be exhausted,moves throughvarious positions and issuccessively, brought under the influence of an oven for removingadsorbed gases, andthen high-frequency coils for the heating ofelectrodes. :In thefinal An object of this invention is to: devisesuch amechanism which is simple, positive in its operation and-which may beadapted for any type of machine. i

In the drawings: Figure 1.is an elevation. view partly in section of myimproved tipping .olf mechanism. I: Figure 2 is a view looking down uponthe mechanism.

are two parallel supporting journals 2 and 3. Within each journal aremounted shafts 4 and 5, respectively. Shaft 4 is adaptedto, beoscillated by means of crank 6, link 7, and lever 8, carrying a camfollower 9, pressed by "spring 11 against a cam 10. Lever 8 is mountedin a journal 12, which is rigidly supported by base 1.

Shaft 5 is adapted to be. reciprocated by bell crank lever 18, carryinga cam follower 14, adapted to cooperate with cam 15. Both cams 10 and15, are mounted on a shaft 16, which may be rotated by suitableactuating mechanism, not shown.

The top of shaft 4 carries a sleeve 17 loose 1y journaled thereon andbearing an arm 18 position, it is customary to have an automatic endfofshaft 4 has rigidly attached thereto an arm- 72'provided with slots 73anl 74 for a purpose tobelater described. This frame consists of twoposts 20, joined at the topl and bottom by yokes 21. Telescopicallymounted within frame 20, is aspring biased mounting .structure,generally designated by 22. This structure comprises two posts 23,sliding in suitable channels within posts 20 of the'frame. Posts 23arerigidly joined togethertbyla yoke 25. Two posts 26 are adapted toslidein channels within posts 23, and, as is evident from the drawing, aredisposed on the Otherside of frame 20.

Posts-26 are rigidly joined together by a yoke 28, into which'isjthreaded an adjusting screw 29. Thelbottom of the adjusting screwterminatesin' a collar 30,.which engages a coil spring 31, whose,bottomend bears against a boss 82,in yoke 25. Centrally disposed of coilspring 31 is a pin33 having its upper portion 84, threaded andterminating in a knurled head 35.. This pin is rigidly fastened to yoke25. j It is clear that-by adjusting screw 29, the tension of spring 31,maybe varied. In this I j way the spring bias of 'yokes 25 and 28, mayCarried-by a base 1, of an exhaust machine to cooperate with a table 39,having a ledge 40 carried by the free end of shaft 5. In this way it isevident that upon rotation of cams 10 and 15, shaft 5 will bereciprocated and impart suitable impulses to yoke 25.

Carried by yoke 28, isa torch 40 having air so and gas supply pipes 41and 42, provided with V adjusting means 43, to control the flame 45.Anbulb retaining assemblyis also carried by yoke 28, and consists oftwo'jaws 45 having their ends connected by a spring 46. The forward endsof the jaws are cut to provide a tapering notched space 47, and acircular space 48, having approximately the same di mensions astubulation 49 of a'vacuum tube 50. As shown, the vacuum tube has itstubu lation 49 inserted into port 51 of turret 52, of the usual exhaustmachine. lhe exhaust connections 53, lead to suitable valve structure,not shown, and thence to pumps in the usual manner.

Jaws 45, of the bulb retaining assembly are a suitably pivoted at 55,and carry light springs 56, adapted to engage the glass portion of tube50. v

In Figure 1, the device is shown as engaging a tube with a flame 45,impinging on tubulation 49. It is evident that when the entire.mechanism is swung inwardly toward vacuum tube 50, tubulation 49'entersportion 47 and forces jaws 45 apart in order to enter The jaws thenspring togetherand Upon thesoftening of the glass in tubulation 49,spring 31 relieves its compression by forcing yoke 28 and .tainerassembly upwardly.

It is evident that vertical adjustment of flame 45, with respect totubulation 49, is

necessary in order that a desirable seal be.

made. This is accomplished by -turning knurled head 35 and threadedmember 34 relatively to screw 29, into which it is thread ed. Bysuitably adjusting screw '29 with V relation to yoke 28. and screw 34,it is possible to adjust the tension of the coil spring 31', and thevheight of torch 45, independently of each other.

It may be desirable to have the exhaust machine operate without havingthe tipping off mechanism operate at the same time. y In order to renderthe tipping off mechanism inoperative, a lever suitably pivoted at andbiased by spring 71, is provided to co operate with'slots 73 and 74 ofarm 72. The mechanism is shown in Figure 2 as being in the inoperativeposition so that while the mechanism is oscillated it does not approachthe tubes close enough toseal them. By op.-

erating lever 7 O the end engaging the slot may be v raised clear andthe entire mechanism swung -1nwardly so that lever 70 engages slot 74,in that case the mechanism in itsoscillatrons will seal the tubes andwithdraw them from the machine. 2 I
